sunpy.Map cannot read inversion result due to missing headers
from sunpy.map import Map
#throws error
m = Map('https://wolke7.leibniz-kis.de/s/C4M6AgWfpXeRAKw/download')
We need a full set of coordinates for each HDU or a mechanism for inheriting headers, not sure if fits supports something like this.
If you just feed the first HDU to Map
it works marvelously.
I guess you could just copy the first header and only replace the btype and extname keywords?
